Abstract

The invention discloses a preparation method for an aggregate of a pattern with a fractal feature containing a complex compound of carboxymethylcellulose. (1) firstly, sodium carboxymethyl cellulose (short for CMCNa) is dissolved in acid aqueous solution and is prepared into acid solution of CMCNa; cationic polyelectrolyte is dissolved into the acid aqueous solution and is prepared into acid solution of cationic polyelectrolyte; then the acid solution of CMCNa is dropped into the acid solution of cationic polyelectrolyte to obtain the complex compound of the CMCNa and the cationic polyelectrolyte; the complex compound is put in de-ionized water, soaked and dried in vacuum; 2) the dried complex compound of the CMCNa and the cationic polyelectrolyte is dissolved into mixed solution consisting aqueous solution with a certain alkali concentration and organic solvent and is prepared into solution; 3) the solution of the complex compound of the CMCNa and the cationic polyelectrolyte is dropped on a clean substrate; then the aggregate of the pattern with fractal characteristic is obtained after the solvent is volatilized under the atmosphere of constant temperature and air.

Description

technical field [0001] The invention relates to the field of fractals and the field of preparation of fractal materials, in particular to a method for preparing aggregates with fractal patterns containing carboxymethyl cellulose complexes. Background technique [0002] Fractals are regarded as the third major scientific discovery after relativity and quantum mechanics in the 20th century. It has been widely used in almost all fields of natural science and social science, and has become one of the frontier research topics in many disciplines in the world today. Fractal theory is dedicated to studying the geometric characteristics of natural structures, and strives to explain and reveal its nonlinear dynamic mechanism from a series of parameters representing geometric characteristics. Fractals is not limited to nonlinear geometry, but goes deep into various fields such as physics, chemistry, biology, medicine, material science, geology, earthquake, engineering technology, weat...
